Sorry, this came directly from a Google Code-In task done back in November that simply asked to transfer the info wiki -> SGML, which I did, and I don't have enough knowledge to check the current status of the things mentioned. The task was just sat in the list, as it had been for months, so I decided to commit it.
Feel free to submit patches. :-)
